A thin spherical conducting shell of radius R has a charge q. Another charge Q is placed at the centre of the shell. The electrostatic potential at a point P a distance R/2 from the centre of the shell is

A

`((q+Q))/(4pi epsilon_(0)) (2)/(R )`

B

`(2Q)/(4pi epsilon_(0)R)`

C

`(2Q)/(4pi epsilon_(0)R)-(2q)/(4pi epsilon_(0)R)`
